II Configuration
1) Proper Earthing
• This device has been designed to operate within safety installations. However, it is
connected to the normal sound system (music, announcements) by a pre-amplifier. If this is
the case, then there must be a check for the presence of correct earthing of the system.
• If there is no earthing of the system, the earthing button (32) must be pressed in.
• If the pre-amplifier is already earthed, the earthing button (32) should be left out
2) Number of connected amplifiers
• You must indicate the number of amplifiers connected to your system
• If you only have one amplifier (insufficient for complying with the EN 60-849 safety
standard), the configuration switch 1 (30) should be in an OFF position (top).
• If you have a second amplifier connected (the minimum required for compliance with EN
60849), the configuration switch 1 (30) should be in an ON position (towards the bottom).
• If you have a safety amplifier connected to this unit, in case of failure of one of the other
two amplifiers, the configuration switch 2 (30) should be in an ON position (towards the
bottom). Otherwise this switch must be off
• For normal operation, all the other switches must be off
3) Emergency Microphone
• If an emergency microphone is being used, connect it to the socket (35) with a 2 pair
insulated cable
• If an emergency microphone is not required in this installation, connect the supplied
resistors to the socket to simulate the presence of the microphone
4) Ways of starting the integrated digital emergency message reader
a) Set off by an Alarm Management Unit (UGA):
The button (38) must be set to NO, i.e. released. See the section “Connection” for
details. The order must come from a continuous current of between 24V and 48V. The
link with the alarm management unit must be at a negative voltage or less than +12V.
b) Set off by a Normally Open dry contact:
The button (38) must be set to NO, i.e. released
c) Set off by a Normally Closed dry contact:
The button (38) must be set to NC or NF, i.e. pressed in.
d) Prealert:
On the configuration switch (30), number 6 must be on in order to receive the prealert
message before the evacuation message. The number 7 is used for setting the delay, 30
seconds on OFF and 5 minutes on ON
5°) Number of connected extension units
a) The rotary switch (31) must indicate the number of extension units being used with the
IS2 base unit.
b) If only this unit is being used, then select 0 on the dial (31).
c) If in addition to the IS2 base unit there is an ES4 and an ES2 unit then select 2 on the
dial. (31).
6°) Economic Mode
In certain cases, you may need to reduce the level of electrical consumption of your
installation. Put the configuration switch (30) number 3 to ON. The amplifiers will only emit
from time to time. It is advised to always stay OFF in order to check the system.
III Connections
•
•
Only connect the mains power and the safety power at the end
Connect the normal sources to inputs 1 and 2
Reminder of wiring for a balanced input
In the case of a balanced source:
In the case of an unbalanced source:
•
•
Connect the modulation liaison outputs 1 and 2 to the power amplifiers
If there is a safety amplifier, connect the modulation output (28) to the safety amplifier
input.
Reminder of wiring for a balanced input
In the case of a balanced source:
In the case of an unbalanced source:
• Connect the 100V outputs of the amplifiers to their respective sockets
Note: The second socket “safety amp” is to be used for an extension unit that doesn’t have a
safety amplifier
Connect the speaker lines to their respective sockets. Ensure that the following points
are carefully followed:
The “COM” socket of the IS device must be connected to the “COM” socket of the end
of line device
The “100V” socket of the IS device must be connected to the “100V” socket of the end
of line device
The “MES” socket of the IS device must be connected to the “MES” socket of the end
of line device
• If this order is not followed then the device may break down or be destroyed
•
If you are using an emergency microphone, connect it. Be careful to use the resistors on
the sockets if you do not have this microphone.
• Only use the MAGPS product (not the MAGPE, MAGPL or any other).
•
•
Connect the type of evacuation start according to the type of alarm management unit
•
•
•
•
The alarm management unit does not start the evacuation order if a fault is detected.
The surveillance of connection faults is made by the evacuation link
An alert of a broadcast default is given by a supervised link « auxiliary contact »
The end of line resistors are supplied by the manufacturer of the Alarm Management Unit
•
•
•
The Alarm Management Unit send the evacuation alert, even if a fault is detected
All system faults are supervised by the Alarm Management Unit
The end of line resistors are supplied by the manufacturer of the Alarm Management Unit
If you have extension units, check the user manual for details of how these are connected
together
• Once all the modules are connected and configured (See configuration above), you can
connect the mains power supply and then the 24V emergency power supply with the + on
the right

IV Operation
1°) Initial Operation
When the system is started, the comfort level can be heard. To check this, ensure that the
modulation source is on. Check that the comfort levels are not at zero.
To test the operation of the amplifiers and the speaker lines, the system must be adjusted. This
adjustment is automatic and started by the configuration switch 5 (30).
To carry out this adjustment, turn switch 5 to (towards the bottom) and reset the unit. To do
this, turn switch 8 to ON and then to OFF. If there are extension units put them in automatic
configuration before the reset.
The system takes a few moments (maximum 3 minutes) to automatically configure, depending
on the number and types of amplifier being used.
Normal modulation is cut during the operation and the green LED (11) is off
The yellow LEDs flash when the configuration is finished and a beep sounds. Press the reset
button (9) to stop the beep.
Put the switch 5 to OFF, then 8 ON and then turn 8 to OFF.
The system starts normally.
XX
2°) Operation with pre-configuration
The system starts automatically after a few seconds
Normal modulation is restored
The green LED is illuminated
The system will carry out tests on different elements of the safety circuit without interrupting
normal operation.
It is possible that the default µ LED lights up. This is due to the initialisation phase. In this
case, press the reset button (9) for at least a second.
3°) Switching to a safety amplifier
When an amplifier breakdown is detected, the system switches to the safety amplifier as long
as it is connected and available.
The safety amplifier must have the power to back up the most powerful amplifier. If you have
a 120W amplifier and a 360W amplifier, the safety amplifier must be 360W.
The operation of the safety is also checked
Once the defective amplifier has been changed, the routing on the safety amplifier can be
restarted with the reset button (9) until the routing has stopped (LED (4) and (6) on the front
panel.
4°) Evacuation Mode
Evacuation mode is started either by a dry contact at the rear (39) (which does not comply
with EN60-849), or by sending a continuous current to the Alarm Management Unit socket
“UGA” (EN60-849 compliant), or by turning the key on the front panel to “manual depart”
(10)
In this case, modulation is cut and the evacuation message is broadcast. The red LED (17)
“evacuation message” is lit.
The tone (43) and volume (42) of the evacuation message are adjusted on the rear panel.
The message is heard on the internal speaker (1) which can be adjusted on the front panel (2)
The message can be stopped at any time by turning the front panel to “Arret Manuel” or
manual stop (8). The message stops even if the order coming from the Alarm Management
Unit continues. In the latter instance, the message restarts if the key is put into position “0”.
5°) Emergency Microphone Mode
This mode can only be started by pressing the operation button on the “MAGPS” unit.
In this case, normal modulation is cut. The evacuation message is cut if it is being broadcast
and the microphone transmits. The red LED “Emergency Microphone” (18) is lit.
The volume (36) and tone (37) level of the microphone can be adjusted on the rear panel.
The message can be heard on the integrated speaker (1), which is adjustable on the front panel
(2).
Normal modulation returns when the button on the microphone is released. If an evacuation
alert is in process, the modulation from the evacuation reader returns.
6°) Surveillance Mode
When the system is neither in evacuation mode through the alarm management unit nor being
used by the emergency desk microphone, operational tests are carried out on fuses, connected
amplifiers, speaker lines, and extension units.
When a fault is detected, the fault is shown on the front panel and a continuous beep is
sounded by the base unit. Press the reset button (9) on the base module for at least one second
to clear the fault. The beep stops.
If another fault appears, the beep returns. Reset, etc….
If the system is no longer responding, reset the complete system with the configuration switch
(30) number 8 button, by turning it on and off on the base unit. Contact your reseller to check
the installation.
V Area Extension
If there are more than 2 speaker zones, you can add up to 9 extension units. To use these units,
please consult the appropriate user manual.
